Air-conditioned shoes

ABSTRACT

This invention involves an air-conditioning system installed in the shoe. This system consists of three air pumps, which are installed in the sole of the shoe, pumping hot air and bad odor out and fresh air in. Another component is an air-conditioning unit located at the back part of the shoe. The basic energy required for the air-conditioning system to function is received from the mechanical energy of the weight of a walking person. Also, additional energy is received from a battery located on the back of the shoe, charged by a battery charger in the sole. All the systems are controlled by an electronic temperature control unit located outside of the shoe. During cold weather conditions, the air-conditioning unit can function as a heat pump, warming the inside of the shoe. The entire system regulates the temperature inside the shoe depending on the weather conditions.

BACKGROUND OF THE INVENTION

Every person, whether walking or jogging, releases heat energy. This heat energy can increase the temperature inside the shoe up to 140 degrees Fahrenheit. This causes problems such as odors, skin problems, tiredness and discomfort. A person also releases mechanical energy during walking or jogging, which can be used to cool off the inside of the shoe. While jogging or walking, people step in different ways—from the heel to the toe of the foot, on the whole foot or on just the toe of the foot. In all three cases, the toe of the foot is used (See FIGS. 1A,1B,2A,2B,2C). For this reason, most of the mechanical components are installed under the toe.

BRIEF SUMMARY OF THE INVENTION

The product that is being presented here involves an air-conditioning system installed inside the shoe. The system will be used to pump fresh air into and stale air out of the shoe, as well as to decrease the temperature inside the shoe. The exact functions are described in the Detailed Description of the Invention.

DETAILED DESCRIPTION OF THE INVENTION

The AC system of the shoes will consist of three parts: exhaust system, AC unit and temperature control. The exhaust system will include three mechanical air pumps—AP1, AP2 and AP3. AP1 and AP2 will be installed under the toe and AP3 will be installed under the heel of the foot (See FIGS. 3A, 5A). The air pumps will resemble rubber balloons, which will contain one-way valve (See FIGS. 8A,8B). AP1 will be used to pump stale air out of the shoe. AP2 and AP3 will be used to pump fresh air into the shoe.

The AC unit will consist of a compressor, filter-dryer, condenser, evaporator, condenser fan and evaporator fan (See FIG. 6A). The AC unit will be located outside of the shoe and will pump cool air into the shoe. It will operate through a 9V DC battery. The battery will be charged by either a portable battery charger or a plug-in battery charger. The portable battery charger will transfer mechanical energy into electrical energy and will be located under the toe.

The temperature control will consist of a digital thermometer, thermostatic sensor (THS), thermostat (TH), foot switch (FS) and solenoid valves (SV1 and SV2) (See FIG. 7A). The temperature control will operate through the same 9V DC battery. The digital thermometer will be located outside of the shoe and will display the temperature inside the shoe. The THS will be located inside the shoe near the toe. The TH will be located outside of the shoe near the thermometer (See FIG. 4A). The solenoid valves will be located inside the shoe and will be used to shut off the incoming air through the tubes going to AP2 and AP3. When the temperature inside the shoe will exceed the set temperature on the TH, the THS will close and will charge the AC unit. Both SV1 and SV2 will open at that time. When the temperature inside the shoe will be the same or less then the set temperature on the TH, the THS will open and discharge the AC unit and close and charge SV1 and SV2. The FS will be closed when the foot will be inside the shoe. 

1. A shoe consisting of an air-conditioning system used to keep the inside of the shoe at a comfortable temperature and free of odor.
 2. An original mechanical air pump system located in the air-conditioning system claimed in claim 1 used for exchanging bad odor and hot air from inside the shoe with fresh air from the outside.
 3. A digital temperature control located in the air-conditioning system claimed in claim 1 and used to regulate the temperature inside the shoe.
 4. A valve system in the air-conditioning system claimed in claim 1 which can convert the air-conditioning unit to a heat pump.
 5. An original mechanical battery charger located in a shoe which converts mechanical energy received from the weight of a walking person to electrical energy.
